Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 Betriebsanweisung

From the Configure Daylight Saving Time Rules window, you can create, change, and delete daylight saving time
(DST) rules that can be used by DHCTs in different DST zones. Setting up the right DST rules enables the DHCTs
in your system to automatically adjust to changes in DST observance. After creating a rule for a particular zone,
apply the rule to one or more hubs. DHCTs will then use the rule of the hub to which they belong.

Important: 



To enable the DHCTs in your system to adjust for DST, you must first create a DST rule for a particular

zone and then you must apply the correct rule to each hub; otherwise, unexpected results can occur.



We strongly recommend that you configure the DST Rules more than 30 days before the time change.

The DNCS will broadcast the DST rules to the DHCTs within 30 days of the DST start and end times that
you specify in the DST Rules window. However, you can add DST rules as necessary at any time. If you
add DST rules within the 30-day window, the DNCS will broadcast the rules to the set-tops immediately.

Note: If the sites you serve do not observe daylight saving time, there is no need to use DST rules. However you
should verify that the hubs in your system use a DST Zone ID setting of "No Zone. Observe Standard Time." For
assistance verifying this setting and changing it if needed, go to 

For additional information on this feature, including the DHCT software versions that support this feature, refer to
